AMENDMENT TO

                              EMPLOYMENT AGREEMENT

         This is an amendment (the "Amendment") made as of December 9, 2003, to
the Employment Agreement (the "Agreement") originally made as of July, 7, 2003,
by and between NeighborCare, Inc. (then known as Genesis Health Ventures, Inc.),
a Pennsylvania corporation (the "Company"), and JOHN ARLOTTA ("Executive").

         Section 10.2 of the Agreement is amended and restated in its entirety
as follows:

                  10.2 Competitive Conduct. During the Term hereof and for a
         period of two (2) years following the Executive's termination of
         employment for any reason, the Executive shall not, except with the
         Company's express prior written consent, directly or indirectly, in any
         capacity, for the benefit of any Person:

                           (a) Solicit any Person with whom Executive had
         substantial contact or about whom Executive acquired confidential
         information during Executive's employment with the Company in any
         manner which interferes or might interfere with such Person's
         relationship with the Company, or in an effort to obtain such Person as
         a customer, supplier, salesman, agent, or representative of any
         business in competition with the Company.

                           (b) Solicit the employment of or hire, whether as an
         employee, officer, director, agent, consultant or independent
         contractor, any person who is, or was at any time during the twelve
         (12) month period preceding the termination of the Executive's
         employment through the expiration of this covenant, an employee,
         consultant, officer or director of the Company or any of its
         subsidiaries and affiliates (except for such employment by the Company
         or any of its subsidiaries and affiliates);

                           (c) Establish, engage, own, manage, operate, join or
         control, or participate in the establishment, ownership (other than as
         the owner of less than one percent (1%) of the stock of a corporation
         whose shares are publicly traded), management, operation or control of,
         or be a director, officer, employee, salesman, agent or representative
         of, or be a consultant to, any Person in any business in competition
         with the Company anywhere in the United States or act or conduct
         himself in any manner which the Executive would have reason to believe
         inimical or contrary to the best interests of the Company. Executive
         acknowledges that this nationwide restriction is reasonable and
         necessary because Executive's responsibilities include strategies for
         geographic expansion throughout the United States. Executive
         acknowledges that the provisions contained in this section will not
         impair Executive's ability to earn a livelihood because Executive has
         the ability to engage in other professional activities that will not
         breach these provisions.

         Section 14 of the Agreement is amended and restated in its entirety as
follows:






         14. Notices. Any notice to be given hereunder shall be in writing and
shall be deemed given when delivered personally, sent by courier or telecopy or
registered or certified mail, postage prepaid, return receipt requested,
